920,96L, Patented May 11, 1909B Inventos warum v WMM 17d/M 3l oi the rod 29. When it is desired to throw the switch point 12, the operator turns the foot lever 30 carrying with it the rod 39 and its toe 31 to throw the pin shield 17 in the required direction. The contact ot the said shoe with said pin shield is a sliding one which continues until the notched portion is reached, whereupon the said shoe will clear said pin shield, and immediately thereafter one ot' the iaring wings 3S of the shoe 3T will have a sliding contact with the pin shield which causes the pendent lever to swing backward and disengage its teeth 3G from the toothed portion 2S of the guide bracket 2li. As soon as this disengagement occurs, the pressure of the spring' Lit) will cause the rod 29 te move upwardly through said guide bracket so as to clear its shoe from any obstruction that may be on the roadbed. To re-set the mechanism, a downward pressure on the end ont the rod 29 which projects through the platform 21 will force said rod to a position where its shoe will again be brought into engagement with the pin shield, and the pivoted pendent lever 35 will swing automatically to a position to cause its teeth to engage with the toothed portion of the guide bracket and thereby hold the entire mechanism in a set position.

Claims l, In a switch operating mechanism, the combination with the switch-point operating rod carrying a projecting element, of a thrower device consisting of a rotatable spring-lifted rod having a toe for engagement with said projecting element, and an automatically released lock for holding said rod depressed against the tension ot its lifting spring.

in a switch operating mechanism, the combination with the switch-point operating rod carrying a projecting element, of a thrower device consisting ot' a rotatable spring-lifted rod having' a toe for engagement with said projecting element, and an automatically released lock comprising a relatively xed toothed surface and a lock lever carried Ywith said rod and having an interlocking engagement with said toothed surface.

3. In a switch operating mechanism, the combination with the switch-point operating rod carrying a projecting element, or a thrower device consisting of a rotatable spring-lifted rod having a toe for engagement with said projecting element, and an automatically released lock comprising a rela tively tixed toothed .surface and a lock lever carried with said rod and having an interlocking engagement with said toothed surface and being also provided with av member for engagement with said projecting element.

4f. ln a .switch operating mechanism, the combination with the switch-point operating rod carrying a projecting element, el a thrower device consisting of a rotatable spring-lifted rod having a toe for engagement with said projecting element, and an automatically released lock comprising a relatively lined toothed snrliacc and a lock lever carried by and depending behind said rotatable rod and havingan interlocking engagement with said toothed snrtace and being also provided with a member lor engagement. with said projecting elemcm.

5. ln a switch operating mcchanism, the. combination with the switch-point operating rod carrying a j irojecting element, of a thrower device consisting oit' a rotatable spring-lifted rod having a toe. lor engagement with said projectingl clement, and an automatically released lock comprising a relativelv iixed toothed surface and a lock lever pivoted to said rotatable rod and haring an interlocking engagianent with said toothed snri'ace. said lock lever beingalso provided with a shoe for engngemenl with said proecting element.

ln a switch operating mechanism, the combination with the swatch-point operatimg` rod carrying a projecting element, ot a thrower device consisting or' a` guide bracket having a spring-lifted rod slid-ably and rotatably mounted therein, and an automatically released lock comprising a toothed snrlace formed on said guide bracket and a lock lever pivoted to and depending behind said spring-lifted rod and provided with a toothed portion adapted to interlock with the toothed suriace of said bracket'. and a shoe carried bv said lock lever and adapted to contact with said projecting element to release. said lever from engagement with said bracket.

7. in a switch operatinY mechanism, the combination ot the switch-point operatiini` rod carrying an opstanding pin, a spring supported shield loosel)v fitting over said pin, and a thrower device.
